Sutton SignWriting

Sutton SignWriting, or SignWriting, was created in 1974 by Valerie Sutton.
It uses visual symbols to represent the handshapes, movements, and facial
expressions of signed languages. SignWriting is based on Sutton DanceWriting,
a notation system for representing dance movements which Valerie Sutton
developed in 1972.

SignWriting is a "movement-writing-alphabet", which can be used
to write any signed language. It is the written form of 27 Sign
Languages. The SignWriting alphabet writes the way the body looks,
when people sign.

SignWriting can be used to write American Sign Language (ASL), British Sign
Language (BSL) or any other variety of sign language. There are newspapers,
magazines, dictionaries, and literature written in SignWriting. It is also
used to teach signs and signed language grammar to novice signers, and can
be used to teach skilled signers other subjects, such as maths, history or English.
